Police investigating the terror attack in Westminster on Wednesday have released a picture of the killer.

Four people, including a police officer, died when Khalid Mosood drove a rented car into crowds on Westminster Bridge and then stabbed the unarmed police officer before being shot dead.

Masood, a father of three, lived with his young family in Luton around 2010/12 and police are appealing for anyone who knew him or any associates to get in touch.

Masood has previously gone by the names of Adrian Elms and Adrian Russell Ajao. He may also be known by a number of other names.

Acting Deputy Commissioner Mark Rowley, appealed for the public’s help. He said: “We named the dead terrorist as Khalid Masood, and as I said, our investigation focuses on understanding his motivation, preparation and his associates.

“Whilst there is no evidence of further threats you will understand our determination to find out if he either:

- Acted totally alone inspired by terrorist propaganda;

- Or, if others have encouraged, supported or directed him;

“At this point I want to appeal specifically to the public.

“We remain keen to hear from anyone who knew Khalid Masood well; understands who his associates were; and can provide us with information about places he has recently visited

“There might well be people out there who did have concerns about Masood but weren’t sure or didn’t feel comfortable for whatever reason in passing information to us.

“I urge anyone with such information to contact us the Anti-Terrorist hotline which is 0800 789 321.”

Detectives are continuing to search a number of addresses linked to the investigation:
